Convinced that her ex-husband Kevin Federline is exposing sons Sean Preston and Jayden James to marijuana, Britney Spears wants the siblings to be tested for drugs.
"Britney believes Kevin's been smoking pot in front of the kids," a friend of the pop singer told Life & Style. "She says she can smell it in the boys' hair and on their clothes when she has her visitation with them."
Is determined to take measures, Britney has "asked the court-appointed monitor and her lawyers if they can prove the kids have been exposed to environments in which drugs have been taken." Greater than that she will also get a sample from Kevin's hair if that will increase her chances to regain the custody of the boys.
Drug expert Marty Brenner confirmed that a sample of hair can provide results of secondhand marijuana. He told Life & Style, "Testing for secondhand marijuana use can be done using a lock of hair. The test must be done within a day or two after exposure. Secondhand smoke would definitely show up, and results usually come back in a couple of days."
Federline currently has primary physical custody of sons Sean Preston and Jayden James, with supervised visitation for Spears. He, however, could lose the custody should Britney's accusation is true.
